When a condition in the body changes from the norm, this information is sent to a control center. Control centers then instructs effectors, such as glands and muscles, to send a response that reverses the change. This is known as negative feedback and is process by which homeostasis takes place.
Diagram above showing the process of homeostasis
Conditions which must be kept constant in the body:
- -Body temperature
- -Blood sugar
- -Carbon dioxide concentration
- -Oxygen concentration
- -Mineral salts
